Operating conditions
•
Compressor must be able to deliver 9 CFM, at 70
to 100 PSI.
•
Use 3/8” air hose between the compressor and the
sander.
•
To avoid moisture damage to the sander, use an
inline filter to trap moisture and an inline oiler to
keep the sander running at top efficiency. These
are placed inline between the compressor and the
sander. See Figure 1.
For further information, see “Air Tools – Instruction and
Care” enclosed with the sander.
Figure 1
Before operation
Disconnect sander from air hose
before making any repair or adjustment. Failure to
comply may cause serious injury.
1. Run compressor and blow out hose before
connecting sander, to clear line of any
contaminants.
2. Before connecting the hose to the sander, add 4 to
5 drops of air tool oil to the air inlet.
3. If an inline oiler is not used, add 4 to 5 drops at the
air inlet for every three to four hours of operation.
4. Adjust head to desired angle and tighten hex
socket cap screw (A, Figure 2), with hex wrench
supplied.
Always tighten hex socket cap
screw firmly after adjustment, or the head
could rotate causing loss of control.
Figure 2
Tracking adjustment
Tracking adjustment requires the
sander to be connected to the hose and running.
Use caution when hands and tools are close to a
running belt. Failure to comply may cause serious
injury.
Belt is tracking properly on all models when centered
on the idle pulley.
1. Loosen set screw with wrench. See Figure 3.
2. With belt running, turn adjusting screw clockwise or
counterclockwise until it is centered on the idler
pulley.
3. Tighten set screw.
Figure 3
Belt replacement
1. Disconnect sander from air source.
2. Loosen hex cap screw (A, Figure 2), turn head 90-
degrees to the handle, and tighten screw to lock.
See Figure 4.
3. Steady the sander with one hand while pushing
down on the idle wheel assembly with the other
until assembly locks in place. See Figure 4.
4. Remove old belt. Install new belt.
5. Press safety lever (A, Figure 4) to tension belt.
